In a grinding machine, there is an electric motor which supplies the motion power to the grinding wheel with the help of a belt and pulley. So when we start the electric motor the motor rotates at a certain rpm 150-15000 RPM, it may change according to the types of grinding machine with the help of v-belt and cone pulley the grinding wheel ...
grinding machines perform the dressing task automatically. The appli ion of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.
If you do not know, a good “rule of thumb” is to discard the wheel when you are 1” away from the recess. Type 6 and 11 Portable Cup Wheels Portable cup wheels must be discarded when the machine’s guard prevents proper grinding. In this case a proper guard will determine discard size by preventing additional grinding on the wheel’s rim.
AG-4 Grinding Machine RPM between 10800 to 12000 Depend on manufactures, in India mostly use Bosch its RPM is 12000 . AG-4 Grinding Wheel RPM between 12500 to 13500 Depend on manufactures . AG-7 Grinding Machine RPM 8500. AG-7 Grinding Wheel RPM 8000 -8500 Not exceed 8500 .
DON& 39;T HANDLE MACHINE CARELESSLY. Racks or hooks should be used to support machine when not in use. DON& 39;T use HEAVY SIDE GRINDING PRESSURE on any Type 1 flat sided wheel. DON& 39;T MOUNT MORE THAN ONE WHEEL on a single arbor. DON& 39;T use a machine for an INAPPROPRIATE APPLICATION. DON& 39;T use a machine WITHOUT PROPER SAFETY GUARD mounted securely in ...
All types of grinding machines, whether pedestal, bench mounted, free-standing or portable, can be potentially hazardous if they are not well maintained and used correctly. In addition to the common hazards of flying particles, dust and sparks, shattering abrasive wheel while in Motion can cause severe injury to both the user and others.
The self-sharpening behaviour of grinding wheel is a necessary part of the grinding machine and the selection of the grinding wheel depends on the work material. The bond between the abrasives is not too strong if the bonds retain the abrasives strongly then it will not allow the abrasive to be pulled out after wear.
DO make sure the machine speed does not exceed the maximum operating speed marked on the wheel; DO use an ANSI B7.1 wheel guard. Position it so it protects the operator. DO be sure wheel hole or threads fit machine arbor properly and that the flanges are clean, flat, undamaged, and the proper type.
